The modular includes a selection of square and round indicators, pushbuttons, rotary switches, emergency stops, and
mushroom-headed pushbuttons.
(It should be noted that in most ethnographically documented cultures, mushrooms and other hallucinogenic substances were considered the catalyst, not the source, of the shaman's visions; instead, it was believed that they merely made the visions possible by opening communication with the Other World.) To have a
mushroom-headed figure emerging from a drum which is actually a rattle is an indication of the relationship between music, the shaman's visions, and the need to see beyond superficial appearances.
